DEVICE FoR o|` L|N G WINDMILLS.

SPECIFICATION forming part of Letters Patent No. 657,563, dated September 11, 1900.

Application tiled November 1898. `Serial No. 697,628. (No model.)

To all whom. t may cori/cern:

Be it knownthat I, SWITHEN C. PETTE- GREW,\acitizen of the United States, residing at Morantown, inthe count-y of Allen, in the State of Kansas, have invented a certain new and useful Device 'for Oiling Windmills, of which the following is a full, clear, and exact description, reference being had tothe accompanying drawings, which form a part of this specification.

My invention relates to a new and useful device for oiling windmills, whereby the working posts of the mill which are located at the top of thetower maybe oiled by an operator from the ground at the loaseI of the tower, thus avoiding the necessity of mounting the tower to reach the oil-cups and supply the oil; and my invention consists of certain features of novelty in the construction and arrangements of parts hereinafter described, and'pointed out in the claims.

Figure 1 represents an elevation of a windmill, the tower being broken, provided with my oiling device. elevation showing the manner of` mounting the parts upon the windmill-head. Fig. 3 represents a detail View showing the manner of mounting and tipping the traveling oil-can. Fig. 4 represents an edge view of the trackslide or traveling bracket. Fig. 5 represents a cross-section on line XX of Fig. 4, showing the manner of connecting the traveling oilcan with the bracket. Fig. 6 represents a top view of the stationary oil-can.

Similar numerals refer to similar parts throughout the several views.

l represents a windmill-tower.

2 represents the windmill-head, mounted on the turn-table 3 on the tower in the usual manner.

4 represents the wind-wheel shaft, on which is mounted the wrist-plate 5.

In the mill shown in the drawings the pump-staff is operated by a connecting-rod 6, extendingv above the Wind-wheel or driving shaft and working in the elevated guideblock 7and operated by the pitman 8, mount ed on the wrist-pin 9 of the wrist-plate 5. This is a quite usual and familiar form of mill-head; but as will appear my oiling device may be applied with equal facility to any mill-head of usual form and construction.

Fig. 2 represents a detail `ing oil-can is drawn up thereon. l in use, the cross-bar 35 is detached from the 10 represents the several oil-cups for oilin g the working parts of the mill.

V11 represents a stationaryoitcan mounted on the arm 12, secured upon the guide-block 7, and thereby raised above the bearings of the mill to which it is desired to apply the oil. Said can is provided .in its bottom with the spoutsor conveyers 13, extending to and arranged to deliver oil into the oil-'cups 10 and other working bearings of the mill, as to the bearing of the connecting-rod in its guideblock and the bearing of the mill-head upon the turn-table. The top of said can is covered, one portion of the cover being hinged, as shown Vat 14 in Fig. 6. A weight l5 is connected by the arm 16 with the hinged portion of the cover, and a lip 17, secured to the body of the can, extends over the same, the weight acting to retain the hinged portion in elevated position against the lip and close to the mouth of the can. A keeper 18 is provided for the arm 16 of the weight.

19 represents an arm secured to the guideblock 7, on which is mounted a block 20.

21 represents a track or way consisting of a pair of parallel wires connected with 'the block 20 and extending to the ground at the base of the tower. The ground end of the wires forming the track may be connected with a cross-bar 35, provided with lugs or hooks 36, arranged to engage a cross-piece of the framework of the tower, and thus hold the track and give it stability as the travel- When not framework ot' the tower, and the track swings free, being unconnected with the tower, and is thus permitted to follow the windmill-head as it turns in the wind. l

Y22 represents a traveling oil-can carried by the gudgeons 23 in the wings 24 of the brackets 25, which embrace and are arranged -to travel on the track. As shown in Figs. 4and 5, the gudgeons are provided with an elongated cap 26 and elongated openings 27 provided in the wing for its insertion, the relation being such that when the can stands upright the caps will be across the openings, so that when the can is hung in the brackets the wires of the track will be` held in their proper relation and the can cannot escape.

TOO

28 represents a cord secured at one end to A the ring 29, attached to the eanator near bottom, and passing over the pulley. 30,` attached to the block 20, the other end is brought back to the hand of the operator. T11is; cQ1d is not all shown, it being familiar to pass a rope over-an elevated pulley. By thiS'OOrd.

the can is drawn up on the track, a springarm 31 being provided on the can extending beyond and bearing against one of vthe ifrzslcik'Y wires to prevent tilting the can as it travels up the track. Near the top of the trackare provided the stops 32 to'limit the upward movement of the can. A trip-arm extends below the stops parallel with the track such distance as to engage the spring-arm'l and release the same from'the wire and permit the can to tilt just before or the brackets reach the'stops, as shown in dotted lines in Fig. 2, and the relation of the paris beingy such that the nozzle of the can will reach the stationary can a sufficient pull on the cord as the traveling can is tilted will press the nozzle upon the lid of the stationary can and overcome the resistance of the weight,'and the contents of the traveling can will be discharged into the stationary can and thence distributed through the spouts 13 to the sevthis device the mill will be oiled much more` eral oil-cups and bearings. r'lhe traveling can being emptied, a weight 34 is provided on its bottom inner edge, sothat upon releasing the cord the can lwill resume its upright posi tion and by gravity return d-own vthe track. r

Thus is provided a simple, convenient, and

economical means for oiling the working parts I of the mill without taking the time and trouble to mount the tower every time the milln must be oiled, and it is obvious that with frequently and the bearings kept in much better condition than where it is necessary to yclimb to the top of the tower to do the oiling, and thus the working parts being more properly oiled the life of the mill is greatly prolonged. l

It is apparentthatwith'slight modifications in details the device maybe applied to any r l, Windmill or to any other machinery wherel there are elevated bearings to be oiled.

f Having thus fully described my device,A l what I claim as my invention, and desire toy secure by Letters Patent, is-

l. A device for oiling windmill-bearings the oil-cups and bearings, a track or Way havvinglonenend mounted abovev said stationary can, brackets arranged 'to travel on said track, a vtraveling oilcan pivotally lmounted betweenv said brackets,`a spring-'arm mounted upon saidv travelingcan and arranged to bear ag'afnli the i'lflackto prevent the tilting of the can,a trip-arm secured upon the track in the path of said spring-arm to release the same from the track at such point that as therelease is made thecan will be tilted and discharge its contents into .the stationary can,

,and means `for propelling said traveling can upon its track, substantially as set forth.

., '-2, VIn a device for oiling windmill-bearings a traek having one end mounted above the bearings, brackets arranged to travel on said n track, an oil-can pivotally mountedbetween vsaid brackets, a spring-arm mounted upon 'said can and arranged to bear against the trackv to prevent tilting of the can, a trip-arm .secured upon 'the track in the path of said spring-'arm to release the same from thetrack, a cord secured to the can and passing over an elevated pulley for elevating the can and tilting the same when said spring-arm is released, and a weighton the can for restoring the same to upright position and returning it down the track, substantially as set forth.

. In a device for oiling windmill-bearings,

l a track consisting of two parallel wire`s,winged brackets embracing said wires and arranged :to travel thereon, an oil-can provided with oppositely-disposed gudgeons arranged to engage elongated openings in said bracketwings, and elongated caps on saidgudgeons to prevent escape from said openings, substantially as set forth.-

` 4. In a device for oiling windmill-bearings, an oil-can ,mounted above the bearings and providedwith a marginal lip, a weighted hingedcover on said can arranged to be opened inwardly and to close against said lip,

and spouts on said can leading tothe oil- -eu ps-and bearings, substantially as set forth.
